The mysterious ancient battlefield, when Lin Feng stepped in again, it felt very different again. The last time he entered the ancient battlefield, he only had hundreds of millions of world combat power.

Therefore, when entering the ancient battlefield, you are cautious and even ready to use the space plate and the time and space mark at any time. You can say that you are extremely cautious. Even the "Sea of ​​Thunder" in the ancient battlefield cannot enter, and there should be the core of the ancient battlefield.

But now, Lin Feng has long been different from the past, with a total of 5 billion world combat power, just like walking in the garden, wandering in the ancient battlefield without feeling any threat.

Finally, Lin Feng came to the "Sea of ​​Thunder" again.

Last time, Lin Feng could not enter the sea of ​​thunder. Just when he approached the sea of ​​thunder, he would feel a severe danger, as if he would face a life-and-death threat once he stepped in.

But now, Lin Feng can hardly feel any danger. Five billion world combat power is enough for him to deal with any threat.

"Let me see the real secret of this ancient battlefield."

Lin Feng was so energetic that he made up his mind.

"Swoosh".

Lin Feng flashed and he raised his foot and stepped into the sea of ​​thunder.

"Rumbling".

Lin Feng stepped into the sea of ​​thunder with one foot, and the entire sea of ​​thunder began to "vibrate", like a drop of water, which suddenly dripped into the boiling hot oil.

The thunder sea was shaking violently, and a terrifying force swept towards Lin Feng in an instant, submerging Lin Feng like a rolling wave.

Lin Feng felt many powerful fluctuations in it, and these boundary rules can still mobilize a certain amount of power, which is simply incredible.

If the master of each rule were probably two-star supreme at the age of ten billion during his lifetime, and it was definitely not one or two, but at least ten, and there were even some vaguely more than one or more.

Therefore, this huge sea of ​​thunder was formed. Without billions of worlds, it was impossible to step into the sea of ​​thunder. Even a billion-level supreme is very dangerous to step into it rashly.

Thunder power swept towards Lin Feng fiercely. But there were shadows of the realm over Lin Feng's head, and terrifying power filled his body. All these thunders were still motionless if they thunders slammed on their bodies.

With a full 5 billion world power, what power can there be to shake it? If the owner of the rules in this sea of ​​thunder is still alive, then Lin Feng is still afraid of it.

But the owner of these rules was dead, and now there are only a few remaining rules left. How could Lin Feng care? However, Lin Feng also saw some clues from so many rules, thus strengthening his inner guess.

This ancient battlefield must be the battlefield of the previous era or the battlefield of the previous era. In short, it must not be the battlefield of the era. With the current situation of this era, how could so many two-star supremes fall?

"The demarcation stones, so many demarcation stones!"

Lin Feng did not forget his purpose. When he stepped into the sea of ​​thunder, he saw that there were bounded stones everywhere, floating in the sea of ​​thunder.

Moreover, these delimited stones are of very high quality, even higher than Lin Feng thought. If you grab a handful of them, they are at least comparable to hundreds of ordinary delimited stones, which can be almost two hundred worlds.

Such a demarcation stone with the highest quality has appeared in large quantities, which is simply unheard of.

Lin Feng entered this ancient battlefield with the purpose of demarcating the boundary stones. Therefore, he was not polite and began to "sweep" the boundary stones in the sea of ​​thunder. One by one, all of them were swept away.

The Thunder Sea is too big, and the deeper it goes, Lin Feng feels the pressure. Fortunately, he has the power of 5 billion worlds to protect him, even if the pressure of the Thunder Sea increases ten times, Lin Feng can withstand it.

And the number of delimited stones he "scaught" is increasing.

Ten thousand, one hundred thousand, one million...

In a blink of an eye, Lin Feng scraped about two million delimited stones. Although the quantity seems to be very small, the quality is excellent. The worst delimited stones can accommodate almost two hundred worlds. What does this mean?

This means that once the world's origin is sufficient, at least 400 million worlds can grow!

Such gains were far beyond Lin Feng's imagination, and this was just the beginning. He could not even explore one-fifth of the thunder sea, and there were still a large number of delimiting stones "waiting" Lin Feng to "scrape".

As Lin Feng continued to deepen, the number of delimiting stones he harvested was getting smaller and smaller, but the quality was getting higher and higher.

"Hmm? This delimiting stone, a one-star delimiting stone?"

Lin Feng's eyes suddenly lit up. He saw several demarcation stones in front of him, which seemed to be unique. Then he grabbed it with his hands and found that there were five demarcation stones, all of which were one-star demarcation stones.

And its quality is very high, it is a million-level delimited stone.

Just these five one-star demarcation stones can increase the combat power of Lin Feng millions or even tens of millions of worlds.

As Lin Feng gradually deepened, he encountered more and more one-star demarcation stones, and the quality was getting higher and higher. This was a huge gain. Of course, Lin Feng would not be polite, and all of them were taken into his pocket. Now what he was most urgent is to improve his strength, so the demarcation stone is the key.

He knew that like the last mission of Supreme Qianyu, he obtained a total of nine two-star demarcation stones. Such a person is almost unattainable. He can be like Supreme Qianyu, Ayong, who has a deep foundation, is already a few, so who would have produced so many two-star demarcation stones?

Therefore, Lin Feng knew very well that there was only one chance that could be encountered but hard to find. If he wanted to get more demarcation stones, he had to find another way.

This mysterious ancient battlefield is the "holy land" that Lin Feng cannot give up. He must "sweep up" all the delimiting stones here before leaving.

"A million-level one-star demarcation stone!"

Finally, Lin Feng was approaching the core area and found some delimited stones of tens of millions. These delimited stones of tens of millions of levels were several or dozens of them.

It was a huge gain, and Lin Feng was naturally overjoyed. But before it was over, Lin Feng continued to go deeper. He was approaching the core area and clearly felt the strong fluctuations in the rules.

This kind of regular fluctuation is greater than the regular fluctuation of any delimiting stone that Lin Feng has contacted.

"Swish".

When Lin Feng dispelled the thunder around him, everything became "calm" within a radius of millions of miles. Lin Feng finally "saw" two demarcation stones.

These two demarcation stones are like stars holding the moon, surrounded by many demarcation stones.

Even the fluctuations of the rules made Lin Feng feel a little pressure, and he had to exert all the power of the realm in his body.
